PARADIM Researchers Show That “Blurrier Is Better” for Atomic Imaging

In a surprising twist on conventional wisdom, researchers using PARADIM's advanced microscopy tools have shown that slightly defocused—or “blurrier”—electron microscopy images can yield more accurate atomic positions. The team demonstrated how altering focus spreads information across the detector, improving the precision of atom localization through computational reconstruction.
